Problems solved by technology

Most of these warning tapes are disposable, some are recycled after use, and some are directly thrown away as garbage, causing plastic environmental pollution
Moreover, traditional warning tape printing generally uses toluene, isopropanol, etc. as solvents, which will also produce waste liquid pollution during production.
[0003] CN105254975A ​​reported that a high-strength warning tape was prepared by blending polyethylene and polypropylene, but it was difficult to degrade automatically after use
CN205223905U describes an LED warning isolation belt assembled from four support frames and shielding belts, which has a good warning effect, but the cost is too high

Abstract

The invention discloses a biodegradable environmentally-friendly warning tape, and belongs to the field of safety engineering application. According to the warning tape, a degradable material PBAT anda degradable milky white masterbatch are added into an outer layer, a middle layer and an inner layer; the outer layer, the middle layer and the inner layer have different formulations, and the warning tape is prepared by separately and uniformly mixing components according to the formulations of the outer layer, the middle layer and the inner layer, co-extruding die heads to form a three-layersfilm, and then color-printing, slitting and packaging. Compared with other warning tapes, the warning tape provided by the invention has the advantages that the PBAT fully biodegradable material is selected, so that the film can be degraded itself after use without causing environmental pollution; at the same time, water-soluble ink is used for printing, and organic solvents such as toluene are replaced by water, therefore, the warning tape is healthy and environmentally-friendly, and has a good application prospect.

Description

technical field [0001] The invention relates to a degradable environmental protection warning tape, relates to the preparation of a degradable environmental protection warning tape by using fully biodegradable raw materials and other additives as a base material, and belongs to the application field of safety engineering. Background technique [0002] The warning tape is used for isolation or warning in special areas of construction sites, traffic accidents, emergencies, etc., and is also used for warnings in high-voltage lines, cables and other outdoor places. Most of these warning tapes are disposable, some are recycled after use, and some are directly thrown away as garbage, causing plastic environmental pollution. Moreover, traditional warning tape printing generally uses toluene, isopropanol, etc. as solvents, and waste liquid pollution will also be generated during production. [0003] CN105254975A ​​reports that a high-strength warning tape is prepared by blending po...
